Featured Field Campaigns and Topical Sessions
Aerosol and Cloud Experiments in the Eastern North Atlantic (ACE-ENA)
For a better understanding of aerosols and low clouds in the remote marine environment, ACE-ENA used measurements from ARM’s Eastern North Atlantic observatory in the Azores and data from ARM’s now-retired Gulfstream-159 (G-1) research aircraft. The campaign took place during two intensive operational periods in summer 2017 and winter 2018.
ACE-ENA data are helping researchers learn more about topics such as the budget of cloud condensation nuclei in the marine boundary layer, cloud and drizzle microphysics, and the effects of aerosols on marine low clouds and precipitation in the region.

Cloud, Aerosol, and Complex Terrain Interactions (CACTI)
From October 2018 through April 2019, CACTI collected ground and aerial data to explore the life cycles of convective clouds in Argentina’s Sierras de Córdoba mountain range. This area is said to spawn the biggest thunderstorms in the world. The campaign featured the first deployment of the second-generation C-Band Scanning ARM Precipitation Radar, which delivers slice-like flat images of the atmosphere. CACTI ran concurrently with Remote sensing of Electrification, Lightning, And Mesoscale/microscale Processes with Adaptive Ground Observations (RELAMPAGO), a campaign funded largely by the National Science Foundation.
With 80 days of deep convection observed, CACTI represents a new wealth of measurements on cloud dynamics and microphysics, ambient thermodynamic and kinematic and surface conditions, and properties of aerosols. The next scenario of focus for the Large-Eddy Simulation (LES) ARM Symbiotic Simulation and Observation (LASSO) activity will be deep convection during CACTI.

Measurements and Modeling of Cloud Condensation Nuclei and Ice-Nucleating Particles
Concentrations of cloud condensation nuclei (CCN), particles on which water vapor can condense to form cloud droplets or ice particles, deeply influence aerosol-cloud interactions and subsequent earth system effects. Ice-nucleating particles (INPs) can originate from sea spray, soot from biomass burning, bacteria, fungi, or carbon-rich organic dust generated during tilling and harvesting agricultural land.
Measurements of INPs and CCN are sparse, contributing to large uncertainties in models of global earth system change. Two sessions at AMS will focus on measurements and modeling of INPs and CCN.
Please note: Most presentations are scheduled to run for five minutes, so the full session times are listed below for planning purposes.
